Have you seen these Air-zookas at several gadget stores and wal-mart ? They are about $20 each. I am going to show you how to make one yourself for less than 10 bucks.
Step 1: What You Will Need
To make it , you will need:
1. A box shaped as a cube...
2. A pair of scissors.
3. A knife.
4. A plastic bag.
5. A screwhook
6. 2 small cylindrical pieces of wood ( you can just cut a pencil in half ).
7. Duct tape
8. A couple of screw nuts
9. A heavy duty rubber band
10.A drafting compass
Step 2: Let's Get Started!
Ok, start by covering all the box edges with duct tape.
Step 3: Fire in the Hole!
Now you will need to make a hole on the top of the box.
Take a ruller and find the center of the box top
Then get your compass and make a circle. Then cut it out.
After you cut it out i recommend puting some duct tape where it was cut.
Step 4: Attaching the Bag
Now you will need to take the plastic bag and lay it on the other , opened side of the box.
Then you must push it a bit inside , but not to much you want to have some plastic bag on the outside so you can stick it on the box.
Now you take your duct tape and you tape the bag on the sides of the box. It must be airtight.
If you have to you can also trim some of the bag.
Step 5: Putting the Hook
Take a piece of duct tape and put it in the center of the bag and make a hole.
Now take the screwhook with a screw nut on it and put through the hole on the bag.
Then attach another screw nut on the screwhook so it won't come off. You also put a screw nut in the end of the screwhook, but that is optional.
Step 6: The Rubber Band
For this step you will need to make 2 holes in two opposite sides of the box.
Then get your rubber band and push it through the two holes. In order for the rubber band to stay you will also need to take these little pieces of wood and put them under each side of the rubber band.
After you have attached the rubber band you will need to hook it with the screwhook.
Congatulations! You have succssesfully made an Air-zooka.
Step 7: How It Works
What you do is , you grab the back of the screwhook, pull it back, and leave it. What this does is, it shoots a massive ball of air and you can actually blow a candle from 10 feet ! Preety awesome isn't it?
